It’s a novel first, a science-fiction novel second: in other words, it has rich characters, a compelling plot, and leaves you with much to think about. The SF element is done seamlessly well with good hard science and coherent thinking about another world and how it might work.

The plot is all about a Jesuit mission to another culture, what happened there, and how it affected the hero, a Jesuit priest and translator.

I suspect Mary Doria Russell gave her story an SF context only because on earth, most of the strange tribes have already been encountered, if not by Jesuits then by their Protestant missionary cousins.

Underlying the whole tale all are deep questions about God, about faith, redemption, surrender and devotion.

It really is a wonderful book, and shows perhaps how hollow much of the rest of the SF universe really is. (Not that that stops me enjoying it: it’s just that this book is so much richer.)

It rightly won prizes. This is the only SF book I would recommend my wife should ever read. It’s a wonderful novel, not to be missed.
